Title: Ｌｉｄａｒデータと画像データの関連付け
IPC: G08G1/16
Filed: 2019-04-23
Abstract: 単眼画像は、画像内に反映されるシーン中のオブジェクトの深度を精度良く決定するための十分な情報を含まないことがよくある。画像データとＬＩＤＡＲデータとを組み合わせることは、カメラに関連するオブジェクトの深度推定値を決定することを可能にすることがある。具体的には、オブジェクトに対応する画像内の関心領域（「ＲＯＩ」）に対応するＬＩＤＡＲポイントは画像データに組み合わされ得る。これらのＬＩＤＡＲポイントは、単眼画像モデル及び／又は事実に従って、又はＬＩＤＡＲポイントのＲＯＩへの投影と関心領域の中心との間の距離に基づいてスコア付けされてよく、深度推定値の精度を改善し得る。これらのスコアをＬＩＤＡＲポイントの荷重メディアンにおける重みとして用いることは、例えば、検出されたオブジェクトと、遮蔽オブジェクト及び／又は背景との間の識別を行うことによって深度推定値の精度を改善し得る。
